Model switching for an engine

[MatterBeam]

Hi.

This is probably the most complicated thing I'll ever do, but here goes:

Is there a way to create the option to switch between several models for an engine part in the VAB?

For example, I drag and drop an engine under a fuel tank. It has parameters A,B,C defined in a .cfg file, and is assigned model 1. I right click on the engine, and I can choose to switch to model 2. It has parameters D, E, F, assigned by another elsewhere in the .cfg file.

I know this option exists, because this 'model switch' is used in procedural fuel tanks.

How is this done? What .cfg code do I need to add to the engine?

You might look at how MFS does it

    MODULE
    {
        name = FSmeshSwitch
        moduleID = 0
        buttonName = Next variant
        previousButtonName = Previous variant
        objectDisplayNames = FH-HL;FHN-HL;FHW-HL
	objects =	     FH-HL;FHN-HL;FHW-HL
	affectColliders = true
	useFuelSwitchModule = true
        fuelTankSetups = 0;1;2
    }

Or just look up Firespitter and look at the wiki on it.

Thank you!

Just to clarify, 'objects' list the general_parameters part name or the mesh model name? Also, are 'useFuelSwitchModule' and 'fuelTankSetups' essential for an engine?

Here's something I made for 4 parts named KRS, KRM, KRL and KRH, with display names Level A-D.

{
name = FSmeshSwitch
moduleID = 0
buttonName = Next
previousButtonName = Prev
objectDisplayNames = Level A; Level B; Level C; Level D
showPreviousButton = true
useFuelSwitchModule = false
objects = KRS; KRM; KRL; KRH
updateSymmetry = true
affectColliders = true
showInfo = true
}

If that don't work you might check looks like he has some spaces

objects = FH-HL;FHN-HL;FHW-HL

EDIT- Well it don't post right and maybe you have the spaces but can see the space in the top post thats funny.
